OIL BURNER Filed DGO. 18, 1926 /C-I'G, 4.

Patented .l an. 1G, 1933 .ares are JAMES C. LYLE AND RICHMOND W.MESSMORE, OF DAYTONA BEACH, FLORIDA OIL BURNER Application filedDecember 18, 1926.

The invention relates to oil burners f or furnaces and the like, and hasfor its principal objects to provide a burner the parts of which aresimple and economical to construct, assemble and install; and which willquickly and thoroughly volatilize the -oil so that the vapor ispractically dry and m the best state for combustion when it reaches theplace of burning. Also the parts are prefer- 0 ably readily separablefor cleaning and the removal of any possible obstruction to the desiredmovement of the oil, vapor and air to enter into the combustion.

lith such objects in view, as well as other advantages which may beincident to the use of the improvements, the invention consists in theparts and combinations thereof hereinafter set forth and claimed, withthe understanding that the several necessary elements constituting thesame may be varied in proportions and arrangement without departing fromthe nature and scope of the invention.

In order to make the invention more clearly understood there are shownin the accompanying dra-wing means for carrying the same into practicaleifect, without limiting the improvements, in their useful applications,to the particular constructions which, for the purpose of explanation,have been made the subject of illustration.

In the said drawing Fig. 1 is a vertical sectional view of a n burnerembodying my invention, installed on the lower part of a furnace.

Fig. 2 is a horizontal section of the same on line 2 2 of Fig. 1.

Fig. 3 is a front view, partly in section, of the support and air intakeof the burner.

Fig. Ll is a similar view of the generator.

Fig. 5 is a similar view of the baflle and vapor conductor.

Fig. 6 is a similar view of the removable top of the generator.

ln said drawing, 1 indicates a port-ion of the base of a furnace, whichmay be of brickwork, and which is formed with a vertical air supplypassage Q. Above this passage is :n mounted the support and air intake 8of the burner, formed with a base Llc which rests on Serial No. 155,684.

the brickwork and with an outwardly flaring upper part 5 which isarranged to deliver the mixture in an upward and slightly outwarddirection so as to cause the products of Vcombustion to impinge on orpass nearby the out r wall of the generator. rl`he support is furtherformed with lugs 6 on which removably rest legs 7 which carry the burnerspaced above the top edge of the support.

The generator 8 is formed at its bottom part with an oil-receivingreceptacle 9 of annular form, bounded on its inner side by an upstandingflange 10. The ange part 10 is continued down below the bottom of theburner and curved upwardly to form a lighting cup 11 in which a smallcharge of oil may be contained and lighted by hand for starting theburner. The legs 7 support vthe bottom of the cup 11, to which they maybe attached. "0

The generator is covered by a removable cap 12.

.Inserted down into the ilange 10 and resting on lugs 10 is a baille 18the top of which extends outward to near the outer wall of the generatorso as to force the moist vapors .arising from the oil into contact withthe heated wall of the generator so as to further vaporize andthoroughly dry the fuel constituent. Said vapor passes thence down '80through the tubular middle portion 14 of the battle.

Oil is supplied to the generator by a pipe 15 which extends upward andsidewise through apertures in the tube 14 and flange 10, so as o togradually deliver oil in the necessary quantity to the generator.

The plane of combustion or grate line is indicated at a?, fc, and atthis plane the descending vapor meets the rising air supplied throughthe intake 3. Here the constituents of combustion are thoroughly mingledand, havin been ignited, burn in an upwardly directed flame whichenvelopes the generator.

16 is .a non-backfire screen mounted within the tubular part 14 of thebaille to prevent any passing of fire up into the generator.

The oil pipe is removable from its engagement with the battle. andgenerator, by removal of the top, and then the battle may be sec removedfrom the generator and the generator may be removed from the intake, andall parts cleaned as may be required. rlhe parts can be reassembled withequal readiness.

The cup ll and the air intake 3 form the upper and lower lips of thecombustion aperture extending around the burner in a hori- Zontalcircular direction.

The proper level of the oil in the receptacle 9 can be maintained by afloat in a known manner.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention, or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

lVhat is claimed is l. An oil burner for furnaces and the like having atubular air intake, and above the saine a generator having an annularoil receptacle, and forming with said intake the upper and lower lips ofan annular combustion aperture which extends around the burner, andmeans for causing the vaporized oil to pass outward against the wall ofthe generator and thence down against the rising air, the mixture thencepassing through said combustion aperture.

2. In an oil burner the combination of a support and air intake, a vaporgenerator spaced above the same to form an annular combustion aperture,an oil pipe delivering into said generator, a vapor baffle in sai-dgenerator extending` outward towards the wall of the generator to causethe vapor to pass against the heated wall of the generator and having atubular vapor-conducting neck extending downward relative to thegenerator to deliver vapor against the air rising through said intake,at a mixing point near said combustion aperture.

3. In an oil burner the combination of asupport and air intake, a vaporgenerator spaced above the same to form an annular combustion apertureand having an annular oil receptacle, an oil pipe delivering into saidreceptacle, a vapor battle in said generator extending outward towardsthe wall of the generator to cause the vapor to pass against the heatedwall of the generator and having a tubular vapor-conducting neckextending downward relative to the generator to deliver vapor againstthe air rising through said intake, at a mixing point near saidcoinbustion aperture.

Il. ln an oil burner the combination of a support and air intake, avapor generator spaced above the saine to form an annular combustionaperture, an oil pipe delivering into said generator, a vapor baffle insaid generator extending outward towards the wall of the generator tocause the vapor to pass against the heated wall of the generator andhaving a tubular vapor-conducting neck extending downward relative tothe generar tor to deliver vapor against the air rising through saidintake, at a mixing point near said combustion aperture, and having acup the upper lip of the combustion aperture.

5. ln an oil burner the combination of a support and air intake, a vaporgenerator removably resting on and spaced above the same to forni anannular combustion aperture, an oil pipe delivering into -saidgenerator, a vapor baffle in said generator extending outward towardsthe wall of the generator to cause the vapor to pass against trie heatedwall of the generator and having a tubular vapor-conducting neckextending downward relative to the generator to deliver vapor againstthe air rising through said intake, at a mixing point near said combnstion aperture.

6. ln an oil burner the combination of a support and air intake, a vaporgenerator spaced above the saine to forni an annular combustionaperture, an oil pipe delivering into said generator, a vapor baffle insaid generator extending outward towards the wall of the generator tocause the vapor to pass against the heated wall of the generator andhaving a tubular vapor-conducting neck extending downward relative toand removably resting on the generator to deliver va por against the airrising through said intake, at a mixing point near said combustionaperture.

7. The combination of the generator having an upstanding tubular flangethe bottom part of which forms a cup under the generator, and a baillein the generator having a tubular part for conducting vapor down fromthe generator and iitting within said flange of the generator.

In testimony whereof we affix our signatures.
